SPECIFICATION forming part of Letters Patent No. 626,499, dated June 6,1899.

Application filed November 19, 1898. $e1'ial No. 696,836. (No m d To(all whom, it may concern:

Be it known that I, ALFRED MORELL, a citizen of the United States,residing at Millbury, in the county of lVorcester and StatebfMassachusetts, have invented certain new and useful Improvements inLooms, of which the following is a specification.

My invention relates to looms, and more particularly to looms providedwith warp stop-motions.

It has been found in the use of warp stopmotions in looms that withwarps which have been colored or dyed the tendency which the threads ofsuch warps have in clinging or matting together interferes with theproper operation of the drop devices of such motions. In order toprevent the adjacent warp-threads from clinging together, I haveinvented a movable rod placed between the stop-motion and the back roll.Said rod has alternate warp-threads pass above and below it. Aback-and-forth motion is given to said rod at intervals, and such motionseparates the adjoining warp-threads from each other,. and they thenpass to the drop devices comparatively free one from another.

In order to illustrate my invention, I have shown it in the drawingcombined with the warp stop-motion shown in United States Letters PatentNo. 599,832, dated March 1, 1898; but I do not limit myself to its usewith the warp stop-motion shown in said patent, as it i is equallyuseful in combination with the other warp stop-motions and may be usedin looms without warp stop-motions.

The drawing represents a portion of the patented warp stop-motion abovereferred to with my improvements combined therewith.

In the drawing the several parts of the warp stop-motion shown aredesignated by the same letters of reference as similar parts shown inthe drawings of Patent No. 599,832, above referred to, and as the sameforms no part of my present invention it is not necessary to describethem herein.

It is only necessary to describe my movable separating-rod and themechanism shown in the drawing for operating the same.

The movable rod or bar 1 is located between the back roll 2 and thewarp-stop-motion mechanism and extends transversely across thewarp-threads 3, which pass above and belowit alternately. Aback-and-forth motion is given to the rod or bar 1 at intervals, and Ihave shown in the drawing mechanism for moving said rod 1 automatically.In this instance each end of the rod 1 is connected by a rod 4 to an armor lever 5, fast on a rockshaft 6. A rocking motion is given to therock-shaft 6 through an arm 7, fast thereon, and a link 8, connectedwith said arm and also with the slotted end 9 of one arm of theangle-lever 9, pivoted at 9". The other arm of said angle-lever 0engages a cam 10 on a driven shaft 11. The revolution of the cam 10,through angle-lever 9, link 8, arm 7, lever 5, and rod 4, communicates aback-and-forth motion to the rod or bar 1 and causes it to separate theadjoining warp-threads from each other.

It will be understood that the details of construction of myimprovements may be varied somewhat from what is shown and de* scribed,if desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a loom, the combination with a rod or bar located intermediate theback roll and the harnesses, above and below which the warp-threadspass, of means to move said rod ALFRED MORELL.
